H. A. TEEPLE SHINGLE Filed May 19. 1927 Patented @ceo 24, i929 PATENT OFFICE HARVEY A., TEEPLE, OF GREENE, IOWA SHNGLE .application ec'l may 39,

The present invention consists of a shingle haring for object the provision of a compact durable shingle which may be flexed under `pressure to i'acilitate laying the shingle 5 and in order to coniorm to building conformations or irregularities such as are encountered at times in shingling roofs, walls, etc.

Another object of the invention is to provide a water-proof and lire-proof shingle l@ which may be subjected to heat in excess of 2O()O l?. Without disintegration or deterioration and without relieving the shingle of any of the desirable characteristics common toshingles of standard construction.

A further object of the invention is to provide a shingle of customary contour which may be manufactured at a very low cost and which will last for an indefinite period of time. 2@ still iur-ther object ofthe invention is to provide a novel method oi making shingles out of standard weatherproof materials, the method being exceedingly. simple to permit expeditious manufacture of the shinglesat a minimum cost.

@ther objects of the invention will be apparent from the following description of the present preferred orm of the invention, taken in connection withk the accompanying drawings, wherein Figure l is a plan view of a shingle con- Vstructed in accordance with the present invention; and,

Figure 2 is a transverse sectional 'view of the same.

The device of the present invention comprises a body or core 3 preferabl made bf metal, such as tin or sheet steel, t ie body or core being offany desired size, but being of a thickness which will` permit it to be freely flexed under pressure.- The core is enveloped in a bituminous casing 4, which is applied to the core by a particular method which will be hereinafter set out. The casing in the composition of rubber, pitch and sand. At-

tention is directed to the fact that the core is completely. enclosed and ifl desired, the shin- 50 une and.

present instance is preferably formed from af 3.827@ Serial l'. 32,602.,

The method employed in making the present shingle consists in advancing the core through an applicatinfr machine which contains a mixture of rubber, sand and pitch. This mixture is agitated in the presence of heat, so as to thoroughly mingle the rubber, sand and pitch. F rom the applicating machine the shingles are passed through rollers which compress the composition on the Core and in View oit-- the inherent cementitious character of the composition, the latter is caused to adhere to the surfaces and edges `of the core, so as to form an envelope for the latter. From the rollers the shingles are ejected on to a conveyor belt which transports the shingles yto a suitable storage place.

The composition is preferably composed of from 2 to, 10 per cent rubber; from 10 to 2O per cent pitch; and from 40 to 80 per cent sand. This composition` is waterand tireproo in addition to providincr an excellent wearing surface capable of withstanding the elements and when applied to a core in accord= ance with the present invention, will not disintegrate or deteriorate in any Way when subjected tov heat, even in excess of 200 F. ln addition, the shingles may be handled with facility by Workmen and may be stored for an indefinite periodof time before being used Without any deterioration whatsoever.

It is, of course, to' be understoodthat the shingle is susceptible of a variety of uses and that various changes may be made therein within the scope of thepresent claim, itbeing essential, however, that the shingle be liexible and both fire-proof and water-proof.

I claim:

A-shingle including aA metal core and a casing, composed of rubber, pitch andsand, I

enveloping the core.
